essential bridge between BLS and long-term survival with good<br />

In terms of airway management the <strong>2010</strong> AHA Guidelines<br />

for CPR and ECC have a major new Class I recommendation<br />

for adults: use of quantitative waveform capnography for<br />

confirmation and monitoring of endotracheal tube placement.<br />

In addition, the use of supraglottic advanced airways continues<br />

to be supported as an alternative to endotracheal intubation<br />

for airway management during CPR. Finally, the routine<br />

use of cricoid pressure during airway management of patients<br />

in cardiac arrest is no longer recommended.<br />

There are several important changes in the <strong>2010</strong> AHA<br />

Guidelines for CPR and ECC regarding management of<br />

symptomatic arrhythmias. On the basis of new evidence of<br />

safety and potential efficacy, adenosine can now be considered<br />

for the diagnosis and treatment of stable undifferentiated<br />

wide-complex tachycardia when the rhythm is regular and the<br />

QRS waveform is monomorphic. For symptomatic or unstable<br />

bradycardia, intravenous (IV) infusion of chronotropic<br />

agents is now recommended as an equally effective alternative<br />

to external pacing when atropine is ineffective.<br />

For <strong>2010</strong> a new circular AHA ACLS Cardiac Arrest Algorithm<br />

has been introduced as an alternative to the traditional<br />

box-and-line format. Both algorithms represent restructured and<br />

simplified formats that focus on interventions that have the<br />

greatest impact on outcome. To that end, emphasis has been<br />

placed on delivery of high-quality CPR with minimal interruptions<br />

and defibrillation of VF/pulseless VT. Vascular access,<br />

drug delivery, and advanced airway placement, while still<br />

recommended, should not cause significant interruptions in chest<br />

compression or delay shocks. In addition, atropine is no longer<br />

recommended for routine use in the management of pulseless<br />

electrical activity (PEA)/asystole.<br />

Real-time monitoring and optimization of CPR quality<br />

using either mechanical parameters (eg, monitoring of chest<br />

compression rate and depth, adequacy of chest wall relaxation,<br />

length and duration of pauses in compression and<br />

number and depth of ventilations delivered) or, when feasible,<br />

physiologic parameters (partial pressure of end-tidal CO 2<br />

[PETCO 2], arterial pressure during the relaxation phase of<br />

chest compressions, or central venous oxygen saturation<br />

[ScvO 2]) are encouraged. When quantitative waveform capnography<br />

is used for adults, guidelines now include recommendations<br />

for monitoring CPR quality and detecting ROSC<br />

based on PETCO 2 values.<br />

Finally the <strong>2010</strong> AHA Guidelines for CPR and ECC continue<br />

to recognize that ACLS does not end when a patient<br />

achieves ROSC. Guidelines for post–cardiac arrest management<br />

have been significantly expanded (see Part 9) and<br />

now include a new Early Post–Cardiac Arrest Treatment<br />

Algorithm.<br />

Post–Cardiac Arrest Care<br />

The <strong>2010</strong> AHA Guidelines for CPR and ECC recognize the<br />

increased importance of systematic care and advancements in<br />

the multispecialty management of patients following ROSC<br />

and admission to the hospital that can affect neurologically<br />

intact survival. Part 9: “Post–Cardiac Arrest Care” recognizes<br />

the importance of bundled goal-oriented management and<br />

interventions to achieve optimal outcome in victims of<br />

cardiac arrest who are admitted to a hospital following<br />

ROSC. We recommend that a comprehensive, structured,<br />

integrated, multidisciplinary system of care should be implemented<br />

in a consistent manner for the treatment of post–<br />

cardiac arrest patients.<br />

Initial and later key objectives of post–cardiac arrest care<br />

include<br />

● Optimizing cardiopulmonary function and vital organ perfusion<br />

after ROSC<br />

● Transportation to an appropriate hospital or critical-care<br />

unit with a comprehensive post–cardiac arrest treatment<br />

system of care<br />

● Identification and intervention for acute coronary syndromes<br />

(ACS)<br />

● Temperature control to optimize neurologic recovery<br />

● Anticipation, treatment, and prevention of multiple organ<br />

dysfunction<br />

The primary goal of a bundled treatment strategy for the<br />

patient after cardiac arrest includes a consistently applied<br />

comprehensive therapeutic plan delivered in a multidisciplinary<br />

environment leading to the return of normal or<br />

near-normal functional status. Patients with suspected ACS<br />

should be triaged to a facility with reperfusion capabilities<br />

and a multidisciplinary team prepared to monitor patients for<br />

multi-organ dysfunction and initiate appropriate post–cardiac<br />

arrest therapy, including hypothermia. Prognostic assessment<br />

in the setting of hypothermia is changing, and experts<br />

qualified in neurologic assessment in this patient population<br />

and integration of prognostic tools are essential for patients,<br />

caregivers, and families and are reviewed in detail in Part 9.<br />

As a guide to therapy, a new algorithm and a table of<br />

integrated goal therapy care were developed.<br />

Stabilization of the Patient With ACS<br />

The <strong>2010</strong> AHA Guidelines for CPR and ECC recommendations<br />

for the evaluation and management of ACS have been<br />

updated to define the scope of training for healthcare providers<br />

who treat patients with suspected or definite ACS within<br />

the first hours after onset of symptoms. Within this context<br />

several important strategies and components of care are<br />

defined and emphasized by these guidelines and include<br />

systems of care for patients with ST-elevation myocardial<br />

infarction (STEMI), prehospital 12-lead electrocardiograms<br />

(ECGs), triage to hospitals capable of performing percutaneous<br />

coronary intervention (PCI), and comprehensive care for<br />

patients following cardiac arrest with confirmed STEMI or<br />

suspected ACS.<br />

A well-organized approach to STEMI care requires integration<br />

of community, EMS, physician, and hospital resources<br />

in a bundled STEMI system of care. An important<br />

and key component of STEMI systems of care is the<br />

performance of prehospital 12-lead ECGs with transmission<br />

or interpretation by EMS providers and advance notification<br />

of the receiving facility. Use of prehospital 12-lead ECGs has<br />

been recommended by the AHA Guidelines for CPR and ECC<br />

since 2000 and has been documented to reduce time to<br />
